I am using db2e with java , i hav this example with me in which the location of database is specified as 'mysample'

String driver = "com.ibm.db2e.jdbc.DB2eDriver";
String url = "jdbc:db2e:mysample";

I try to search but i couldnt find where this database and tables inside it are on my computer, where should it be?
Also i would like to change this path to some other location e.g
String url = "jdbc:db2e://";

So that i can create database on some folder in my machine or any other machine (which act as server) and i store my data there.
